The 2012 Giants hit 70 percent of their homers in road games. In the postseason, it’s now 75 percent.

Angel Pagan, Gregor Blanco and Pablo Sandoval all went deep in Wednesday’s 8-3 win in Cincinnati, giving the Giants their first homers since Buster Posey hit one in Game 1 in San Francisco.

The Giants also got five doubles in the game, including two from Joaquin Arias. It’s just the fourth time all year they’ve done that. The eight extra-base hits was a new season high.

Pagan and Sandoval became the sixth and seventh players in franchise history to homer and double in the same postseason game, joining Hall of Famers Mel Ott and Willie Mays, plus three very good players in Will Clark, Jeff Kent and Pat Burrell.

Blash, 28, was acquired by the Yankees from the Padres back in December in the Chase Headley trade. In trading Blash to the Angels, the Yankees were able to free up a spot on the 40-man roster for Brandon Drury, the infielder they acquired as part of a three-team trade with the Diamondbacks and Rays on Tuesday.

Over parts of two seasons in the majors, Blash has hit an underwhelming .200/.323/.336 in 279 plate appearances. He will try to play his way into a bench role for the Angels this spring.
